And on this farm he had a champ . W/a txtr here , and BFF there . Here a text , there a text , erywhere a text-text ! '' in 60 seconds .

Brianna took home $ 50,000 and will compete in the LG Text For Good Challenge , where she will have the chance to double her prize money and win an additional $ 50,000 for a charity of her choice , the technology company said .
